//! Skill system — predefined prompt templates loaded from YAML frontmatter + Markdown body files.
//!
//! Skills are declarative data (no trait, no execute method). They are loaded at startup,
//! their descriptions are injected into the system prompt, and their full content is injected
//! when a user triggers them via a slash command.
